示例1:
string[] fruits = { "apple", "banana", "mango", "orange",
"passionfruit", "grape" };
// Project an anonymous type that contains the
// index of the string in the source array, and
// a string that contains the same number of characters
// as the string's index in the source array.
var query =
fruits.AsQueryable()
.Select((fruit, index) =>
new { index, str = fruit.Substring(0, index) });
foreach (var obj in query)
Console.WriteLine("{0}", obj);输出：
{ index = 0, str = }
{ index = 1, str = b }
{ index = 2, str = ma }
{ index = 3, str = ora }
{ index = 4, str = pass }
{ index = 5, str = grape }
示例2:
List<int> range =
new List<int> { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
// Project the square of each int value.
IEnumerable<int> squares =
range.AsQueryable().Select(x => x * x);
foreach (int num in squares)
Console.WriteLine(num);输出：
